Explanation:

Given:

(9, 8)

The slope-intercept form of an equation is given as

y = mx + c

Firstly, we need to find the slope

Slope = rise / run

Slope = 8/9

Hence, slope is 8/9

let x1 = 9, and y1 = 8

(y - y1) = m(x - x1)

(y - 8) = 8/9(x - 9)

y - 8 = 8/9x - 8/9*9

y - 8 = 8/9x - 8

y = 8/9x - 8 + 8

y = 8/9x + 0

y = 8/9x

Hence, (9, 8) does not make the equatio y = 8 true
